Linzess is prescribed for the treatment of irritable bowel syndrome with constipation (IBS-C) in adults and chronic idiopathic constipation (CIC) [1][2].
What is Linzess and How Does it Work?
Linzess is a medication that belongs to a class of drugs called guanylate cyclase-C (GC-C) agonists [1]. It works by increasing the amount of fluid in the intestines, which helps to soften stool and stimulate bowel movements [2]. This mechanism helps to relieve abdominal pain, discomfort, and constipation associated with IBS-C and CIC [1].
When Does Linzess Patent Exclusivity End?

According to DrugPatentWatch.com, the earliest key patent for Linzess is set to expire in late 2027, with others extending further into the future. However, the exact date of market exclusivity loss can be affected by patent challenges and litigation [3].
Can Generics of Linzess Be Available Before Patent Expiry?
